A Wired article citing Wesley Clark's thoughts on physics, the speed of light, and time travel (via Instapundit):

During a whirlwind campaign swing Saturday through New Hampshire, Clark, the newest Democratic presidential candidate, gave supporters one of the first glimpses into his views on technology.

...

"I still believe in e=mc², but I can't believe that in all of human history, we'll never ever be able to go beyond the speed of light to reach where we want to go," said Clark. "I happen to believe that mankind can do it."

"I've argued with physicists about it, I've argued with best friends about it. I just have to believe it. It's my only faith-based initiative." Clark's comment prompted laughter and applause from the gathering.

Gary Melnick, a senior astrophysicist at the Harvard-Smithsonian Center for Astrophysics, said Clark's faith in the possibility of time travel was "probably based more on his imagination than on physics."

While Clark's belief may stem from his knowledge of sophisticated military projects, there's no evidence to suggest that humans can exceed the speed of light, said Melnick. In fact, considerable evidence posits that time travel is impossible, he said.

"Even if Clark becomes president, I doubt it would be within his powers to repeal the powers of physics," said Melnick, whose research has focused on interstellar clouds and the formation of stars and planets.

How about working on viable alternative energy sources, increased IT and communications technology, the plethora of potential from biotechnology...before tackling time travel?

The article says that Clark's answer was in response to a question about NASA. I like the fact that he's a pro-tech candidate, but for Pete's sake, couldn't he have talked about the frontiers of plausible technological breakthroughs, instead of breaking the light barrier?
